E – 3145 V2G – An Important Energy Storage Contributor

There are currently approximately 6 million electric vehicles (not counting the electric bicycles, scooters, unicycles and other non-automobile transportation devices) on the road in the United States and it is projected that by 2035, this number will increase to over 78.5 million. [1]  Since more than 280 million vehicles are presently registered in the United States, if the present trend in EV purchase continues until 2045, the entire fleet of vehicles could be replaced with EVs.  One might initially be concerned about any negative effects this transition might have on the electrical grid, but, in fact, the positive effects will likely outweigh any negative effects.

The goal of this course will be to demonstrate how the adoption of EVs and incorporation of them in a V2G (Vehicle to Grid) manner can result in an overall positive contribution to the modern electrical grid.

Currently, most EVs on the road only USE electricity from the grid.  However, the V2G scenario is based upon addition of an inverter in order to convert stored energy in the vehicle batteries back to AC that can be returned to the grid when the grid needs it.  This presentation will summarize the existing and planned storage mechanisms that will be needed to maintain grid reliability and show the significant contribution that can be made by V2G.
